Le dispositif de direction comporte: une entretoise, qui présente une surface périphérique intérieure et est installée par insertion sur l'extérieur de la surface périphérique extérieure de l'extrémité de la colonne de direction se situant à l'arrière de la carrosserie du véhicule, et une surface périphérique extérieure, qui est formée aux dimensions de diamètre extérieur, et à l'extérieur de laquelle la surface périphérique intérieure d'une partie d'insertion prévue sur le commutateur combiné peut être insérée; et un mécanisme de prévention de rotation, qui permet de prévenir une rotation de l'entretoise par rapport à la colonne de direction. Par conséquent, l'invention permet d'installer le même commutateur combiné sur une pluralité de types de colonnes présentant différentes dimensions de diamètre extérieur.
